Question
The following information was collected regarding CEPA performance and final LSM 1003 marks. Calculate the following to 2 decimal places unless otherwise indicated. Find the correlation coefficient Find the coefficient of determination Find the regression equation What percent of my data does not fit the regression model? If Adel earned 200 on CEPA what do you think he would earn in LSM 1003 base done the regression equation? What type of relationship is this model? Which CEPA score is more reliable based on the data set 180 or 240? R = 0.83 r^2 = 0.08 180 68% A strong positive linear relationship 32% r^2 = 0.83 y = 21.56 x + 0.32 r = 0.68 4312.32 85.56 17% y = 0 32 x + 21. 56 A strong negative e linear relationship A weak positive linear relationship 240 A weak negative linear relationshipExplanation / Answer
The correlation Coefficeint is r = 0.83 Answer: Option (A)
The coefficient of determination r2 = 0.68 Answer: Option (B)
The regression equation is Y = 21.56 + 0.32 X Answer: Option (M)
The percent of my data does not fit the regression model is 32% Answer: Option (F)
If Adel earned 200 on CEPA then The Predict LSM 1003 based on the regression equation is
Y = 21.56 + 0.32 (200) = 85.56 Answer: Option (K)
The relationship of this model is A strong positive linear relationship between them
Answer: Option (E)
Correct Answer 180 since this is in the variable is X i.e. SEPA SCORE. 240 is extrapolation point.
Answer: Option (C)
